Dual Very-High Speed, High-Current Peripheral Drivers

The SN55451B through SN55454B and SN75451B through SN75454B are dual peripheral drivers designed for use in systems that employ TTL Logic This family is functionally interchangeable with and replaces the SN75450 family and the SN75450A family devices manufactured previously. The speed of the devices is equal to that of the SN75450 family, and the parts are designed to ensure freedom from latch-up. Diode-clamped inputs simplify circuit design. Typical applications include high-speed LogicBuffersPower DriversRelay Drivers lamp drivers, MOS drivers, Line Drivers and memory drivers.The SN55451BSN75451BSN55452BSN75452BSN55453BSN75453B and SN55454BSN75454B are dual peripheral AND, NAND, OR, and NOR drivers, respectively (assuming positive logic), with the output of the LogicGates internally connected to the bases of the NPN output TransistorsThe SN55' drivers are characterized for operation over the full military range of -55C to 125C. The SN75' drivers are characterized for operation from 0C to 70C. By Texas Instruments
